Save 5p per litre at Morrisons or 10p per litre at Tesco or Sainsbury's

Sainsbury’s customers can save 10p per litre on fuel when they spend £60 or more in a single transaction either online or in store between 22 and 27 August.

Eligible customers will receive a coupon at the checkout or when they receive their groceries, which need to be delivered by the 27th.

It’s best to keep your coupon close to hand so you don’t forget to use it as it is only valid at Sainsbury’s petrol stations for up to 14 days after your shop.

Similar to previous promotions, exclusions apply, and the coupon is not valid at Pay@Pump.

But you can top up your car with unleaded petrol, super unleaded petrol, diesel or LPG up to a maximum of 100 litres – and collect one Nectar point for every litre purchased.  

Morrisons customers can save 5p a litre on fuel when they spend £40 in store (not online) until Sunday, 25 August.

Eligible customers will receive a voucher that allows them to top up for less, but it's only valid until 1 September. 

If you don't shop at Morrisons or have a Tesco store nearby, you could save even more on fuel. 

Tesco customers can save 10p per litre on fuel when they spend £60 or more on groceries in a single shop either in-store or online until 25 August.

Of course, any groceries ordered online need to be delivered or collected by 25 August.

The coupon is only valid for up to 100 litres of fuel (so a maximum saving of £10) and must be used within two weeks of purchase, so make you sure you don’t forget to use it!

Unfortunately, there are some exclusions from the qualifying spend, including gift cards and prescription medicines.

Tesco says coupons are not issued at Express stores selling Esso fuel and cannot be redeemed at these stores or used for Pay at Pump transactions.

The promotion by Tesco follows a warning from the RAC, which revealed petrol and diesel prices rose in July, but pump prices are still cheaper compared to the start of June.

Petrol station loyalty cards

Various petrol stations offer loyalty cards, which can help you save on the cost of filling up.

For example, Texaco operates the Star Rewards scheme. You get one point for every litre of petrol or diesel that you buy.

Once you hit 500 points, you can turn that into a £5 voucher to use the next time you fill the car. You'll get 50 bonus points for signing up, getting you well on the way to the 500-point mark.

Alternatively, you can convert those points into vouchers for retailers including Argos and Marks & Spencer.

Shell operates a similar scheme called Shell Drivers Club, where two points are effectively worth 1p.

You'll get one point for every litre of Shell Regular diesel, Shell Regular unleaded and Shell Autogas LPG, or two points for every litre of V-Power unleaded or diesel.

Further points can be earned when you spend in the service station, or if you get your car washed. Finally, you can bag a bonus 200 points by registering your card online. You can then convert 500 points into a £2.50 voucher.

In 2019, BP is to drop out of the Nectar point scheme and launch its own loyalty scheme, although further details are yet to be confirmed. In June, Esso will join the Nectar point scheme.
